Description

Off-R

oad

Program

Riders who want to get more out of their SMR should look no farther than the Akrapovic Racing or Evolution exhaust system. The systems offer increased performance, lower weight and an interesting styling enhancement. The sys-tems include a noise damper for the European and other non-American mar-kets, and an approved spark arrester for the US market, which is marked on the muffler with a laser engraving.

PERFORMANCE

Measurements of the Akrapovic RACING system on the HUSQVARNA SMR 450 (with muffler insert):

Power & Torque: the system provides an increase throughout the entire rpm range. The boost is especially noticeable around 4000 rpm, where the dropouts in the stock power and torque curves are filled. Max. increased power of 4.2 HP is measured at 4400 rpm.

CONFIGURATION

The system is configured 2-1 using a combination of stainless steel and titanium. The dual conical stainless steel (Racing) or titanium (Evolution) header tubes are joined into one and led into a conical stainless steel (Racing) or titanium (Evolution) link pipe. The link pipe then leads into the titanium muffler. The connections are sleeve joints held together with silicon-shielded tensioning springs. The muffler outer sleeve is titanium, as are the inner perforation and the inlet and outlet cap. The muffler is at-tached to the frame using two carbon-fiber clamps.The system includes a noise damper for the European and other non-American mar-kets, and an approved spark arrester for the US market, which is marked on the muf-fler with a laser engraving.

Technical specifications of Akrapovic exhaust systems and related products subject to change without notice.
